GST Registration involves enlisting your enterprise under the Goods and Services Tax regulations. Upon enrollment, your company receives a unique GST Identification Number (GSTIN), a 15-digit code issued by authorities.
This number is your business's tax ID. You will also need it to collect GST from customers, get input tax credits, file your GST returns, and stay on the right side of GST rules.
Basically, getting a GST registration lets your business legally operate under the GST tax system.
Why Was GST Introduced in the First Place?
The Pre-GST Era
Before GST, India had more than a dozen indirect taxes—VAT, service tax, excise duty, CST, octroi, and many more. This led to:
The GST Reform
GST solved these by replacing most indirect taxes with a single unified tax. It ensures:
- One nation, one tax
- Seamless flow of input tax credit
- Transparent taxation
- Reduced cascading of taxes & Simplified compliance
Due to this reform, enterprises fulfilling certain criteria are now obligated to enroll in GST.
